The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Current conservation status
The threat classification status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Endemic. New Zealand: South Island (in the east from Marlborough to Central Otago)
Lowland to subalopine in tussock-grassland, on river terraces and amongst rocks.
Wetland plant indicator status rating
Information derived from the revised national wetland plant list prepared to assist councils in delineating and monitoring wetlands (Clarkson et al., 2021 Manaaki Whenua – Landcare Research Contract Report LC3975 for Hawke’s Bay Regional Council). The national plant list categorises plants by the extent to which they are found in wetlands and not ‘drylands’. The indicator status ratings are OBL (obligate wetland), FACW (facultative wetland), FAC (facultative), FACU (facultative upland), and UPL (obligate upland).
FACU: Facultative Upland
Occasionally is a hydrophyte but usually occurs in uplands (non-wetlands).
Perennial herb with radical, rosulate tufts of leaves, sometimes alternate on elongated stems (shade form). Leaves concolorous or paler beneath, yellow-green, green to red-green, turning glaucous on drying; more or less petiolate, lamina 10 × 2 to 40 × 10 mm, linear to elliptic, gradually narrowed to petiole as long as the lamina or longer, margins entire or subentire, thickened, teeth if present, inconspicuous. Flowers insect-pollinated, narrowly campanulate-rotate, corolla pale flax blue to pale blue-violet, often with white zoning and deeper coloured veins, or all white, 12-17 mm diameter, 10-20 mm long, corolla tube 4 × 3 to 10 × 6 mm, lobes 6 × 3 to 12 × 5 mm; style equal in length to corolla tube, lobes 2 or 3. Calyx lobes less than ¼ corolla length; capsule domed cylindric, 6-8 × 4 mm. Seeds 0.5 mm long, ellipsoid, smooth, glossy brown when mature.
Wahlenbergia albomarginata subsp. albomarginata is distinguished from subsp. decora J.A.Pettersen, subsp. flexilis (Petrie) J.A.Pettersen, subsp. laxa (G.Simpson) J.A.Pettersen and subsp. olivina J.A.Petetrsen by its inland eastern South Island distribution (and virtual restriction within this area to low-rainfall regions), and by its entire, linear to elliptic leaves which are often white margined. All of the W. albomarginata subspecies recognised by Petterson (1997), except perhaps the ultramafic endemic subsp. olivina, require a thorough revision, as many of the characters used to separate them are overlapping.
November – April
December - April
Easily grown from tip cuttings and the division of whole plants. Fresh seed germinates readily. Being insect-pollinated and having an indigenous pollinator, cultivated plants rarely set seed.
wahlenbergia: Named in honour of Wahlenberg, a Swedish botanist and author of A Botany of Lapland.
albomarginata: From the Latin albus ‘white’ and marginatus ‘having a border or margin’ meaning something with a white margin, often referring to leaves
